the OMM Core Fleece Jacket

A new concept in active insulation, OMM Core Range is completely made of PRIMALOFT NEXT ultralight insulating fabric. Built from a synthetic plume woven through a knitted mesh, Core provides the warmth of a fleece but less than half the weight. Paired with a shell, Core is an incredibly effective insulator; but thanks to almost total air permeability, the lightest breeze can remove that heat. This allows you to keep your core bearing on even after you have warmed up and you can regulate heat by removing / unpacking the shell with low bulk (eg Sonic windproof at 49g). A real valley to the top. Core works wet or dry with incredible moisture-transporting properties to ensure that you do not get wet for a long time.

Core Fleece Jacket uses 125g PRIMALOFT® NEXT insulating fabric technology.
